if和whether的用法区别口诀:在引导主语从句时,一般用whether,而不用if。在引导宾语从句时,一般情况下whether和if可以通用。从句中含有or,强调选择,这里只宜用whether;宾语从句中包括一个if从句,则宜用whether)等。
if与whether用法的细致区别:
1、在引导主语从句、表语从句、同位语从句时一般用whether不用if。
2、引导宾语从句,一般既可用whether也可用if。
3、or not放在whether所引导的.从句句尾,则可以用if来替换。
4、whether和or一起还有“不管”之意,引导让步状语从句。
5、用在动词不定式之前时用whether不用if。

whether和if的用法分析 whether和if都可以引导宾语从句,表示“是否”,在口语或间接引语中两者可以互换使用。如: I wonder if / whether I can get some advice from you. Ask him whether / if he can come. 但在有些情况下,whether和if的用法有一定区别。 1. whether引导的从句常可以与连词or或or not直接连用,而if一般不能。如: 正: Let me know whether you can come or not. 误: Let me know if you can come or not. 2. 当宾语从句提到句首时,只能用whether引导,而不能用if。如: 正: Whether it is true or not, I can’t tell. 误: If it is true or not, I can’t tell. 3. whether可以引导带to的不定式,if则不能。如: 正: I don’t know whether to accept or refuse. 误: I don’t know if to accept or refuse. 4. whether及其引导的成分可放于介词之后,作介词的宾语,但if不能。如: 正: I worry about whether I hurt her feelings. 误: I worry about if I hurt her feelings. 5. whether可以引导从句,作主语、表语或同位语,而if不能。如: 正: It was uncertain whether he would come. 误: It was uncertain if he would come. 正: His first question was whether Tom had arrived yet. 误: His first question was if Tom had arrived yet. 正: We must consider the question whether we will take these measures. 误: We must consider the question if we will take these measures.
